Concern for the future of reef-building corals in conditions of rising sea temperatures combined with recent technological advances has led to a renewed interest in documenting the biodiversity of mesophotic coral ecosystems (MCEs) and their potential to provide lineage continuation for coral taxa. Here, we examine species diversity of staghorn corals (genera Acropora and Isopora) in the mesoph...

OBJECTIVE This present study has aimed to assess the state of acute phase markers and oxidative stress in patients with kidney stones. MATERIAL AND METHODS A prospective study was carried out on 100 patients with kidney stones and 25 healthy controls. Albumin, ß2 microglobulin, Gamma-glutamyl transpepsidase, Lactate dehydrogenase, Tumor necrosis factor alpha, Interleukin 1 and Interleukin-6 w...

Background: Percutaneous nephrolithotomy (PCNL) is a procedure typically performed under general anesthesia (GA); however, many patients might be considered unfit for GA and locoregional anesthesia is their only chance to have the procedure done. Case Presentation: A 60-year-old Middle-Eastern female with end-stage lung disease underwent evaluation for lung transplant; she was found to have sev...

OBJECTIVES (1) To evaluate the safety and efficacy of supine percutaneous nephrostomy, nephrolithotomy, and combined percutaneous nephrolithotomy and ureteroscopic lithotripsy. (2) To describe the skill-acquiring process in supine procedures and share our initial experience. DESIGN Three-staged case series with prospective data collection. SETTING Two public hospitals in Hong Kong. PATIEN...

A urinoma is a collection of urine outside the urinary tract as a result of disruption of the collecting system. Obstructive causes of urine extravasation secondary to stones are not unseen but display a delayed diagnosis due to the gradual onset of symptoms, which can mimic pyelonephritis. We present the case of a 70-year-old female patient who was admitted to hospital with symptoms of right l...

OBJECTIVE To evaluate the prevalence of metabolic disorders in patients with staghorn calculi treated at the Regional Center of Lithiasis Metabolic Studies in central region of Såo Paulo State, Brazil. MATERIALS AND METHODS Between February 2000 and February 2008, 630 patients with urinary calculi were evaluated in the lithiasis outpatient clinic. Thirty-seven of them had staghorn calculi (35...

Problem statement: The formation of a urinary stone, known as nephrolithiasis, urolithiasis, renal calculi or kidney stone is a serious, debilitating problem in all societies throughout the world. Struvite or Ammonium Magnesium Phosphate Hexahydrate (AMPH) is one of the components of urinary stone (calculi). Struvite stones are commonly found in women. Struvites form in humans as a result of ur...

Dear Editor: We read the study ‘‘Combination of Extracorporeal Shockwave Lithotripsy and Ureteroscopy for Large Staghorn Calculi in a Pediatric Patient: Case Report’’ with great interest. Stone diseases in the pediatric population are an important clinical problem. The diseases are recurrent in nature, and they are generally related to metabolic anomalies. Treatment options are decided based on...

Objective: The Hounsfield unit (HU) is the most common value to assess stone formation and a predictive factor for management success. In this study, it was aimed investigate prediction of hardness using systemic inflammatory response markers. Methods: 192 patients (61 female 131 male) who underwent conventional percutaneous nephrolithotomy (PCNL) between 2015 2020 were reviewed retrospectively...

BACKGROUND Urolithiasis in pediatric population is a serious problem with the incidence increased these years. In the management of larger stones (diameters >2 cm), percutaneous nephrolithotomy (PCNL) is considered to be the gold standard. This study aimed to investigate the efficacy and safety of mini-PCNL under total ultrasonography in patients aged <3 years. METHODS We reviewed 68 patients...
